PERMUTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 336,858, dated February 23, 1886.

Application filed June 17, 1885. Serial No. 168,974. (ModeL) To all whom it may concern.-

Be it known that I, JOHN H. JULIAN, a citizen of the United States, residing at Troy, in the county of Miami and State'of Ohio, have invented certain new and useful Improvements in Permutation-Padlocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings represents my improved padlock in elevation. Fig. 2 is a vertical section of the same on line a; a, Fig. 1.

. Figs. 3,4, 5, 6, 7, 8, and 9 are detail views of the various parts detached.

This invention relates to permutation-padlocks; and it consists in the construction and novel combination of parts, as will be hereinafter set forth and claimed.

Referring by letter to the accompanying drawings, A designates the stafi" or journal, which is provided with a head, A, at its lower end, a threaded upper end, B, a rectangular portion, B, below the threaded portion, and a vertical groove, 0, in one side of said staff, which groove extends from the head to the shoulder O.

D designates thelock-case, which is provided with a central rectangular opening, D, in its upper end for the rectangular portion B of the staff A, and recesses E and F, through which the arms of the hasp G are inserted and removed to lock and unlock the padlock.

H designates the graduated lower or base tumbler, which is provided in this instance with a scale, I, which is divided into sections of ten spaces each, and the entire scale numbers fifty scale-marks.

At its lower end the shell or lock-case D is provided with a stop-mark, I, by which to guide the operator who desires to open or close the lock, it being necessary to align the notches or seats in the tumblers to insert, and also to remove, the hasp of the lock.

The base-tumbler H is provided on its upper face with a stop-pin, H, which is located quite near to the central opening, H made therein, and this stop-pin H enters either one of four vertical recesses or slots,J,in the sleeve or collar J, formed on the under face of the tumbler L. These recesses J are open at their lower ends, and either one of them may be made to fit over the stop-pin H, so that four changes of the combination may be effected at this point without making changesin the stop pin described hereinafter in the other tumblers,by moving the stop-pin from one to another of the holes or seats 0.

XVashers K are interposed between the incased tumblers, and these washers are pro vided with V-shaped projections K, which fit the groove 0 in the staff A, and prevent the washers from turning with the tumblers.

Each of the interior tumblers,L M N,is provided with six holes, 0, in either one ofwhich the stop-pin P may be placed, and in one of the adjacent holes the lower or downwardly 7o projecting pin, P, of each tumbler may be seated. Aspring, Q, isemployed between the graduated tumbler and the one next to it,which is designed to hold the tumblers together with sufficient force to cause them to operate properly without too much binding.

The cap-plate R screws onto the grooved threaded staff, and cannot be removed when the hasp G is in place in its seat. The capplate is in disk form witha central opening, in wlrich the staff A has its upper bearing. This cap -plate has diametricallyopposed notches in its periphery,which,when in proper position, permit the insertion of the hasp in the lock-case, and by the engagement of said notches with the hasp the cap-plate cannot be unscrewed. One arm of the hasp G is provided with a guard, S, for each tumbler, except the base-tumbler, and the other arm of the said hasp has one guard, S, for the upper tumbler of the set of tumblers.

As an illustration of the manner of opening the lock,the following is given as to one combination: The lock is set to the numbers 45, 22, and 9. To open the lock with this combination, turn around to the right four times and stop at 45; reverse, passing 45 once, and stop at 22; reverse, do not stop at 22, and stop at 9, and the hasp may be withdrawn.

Should the tumblers be turned or misplaced 10o while the hasp is out, the same combination must be employed to align the notches to per-- what I claim as new, and desire to secure by Letters Patent of the United States, is-

The combination, with the lock-case having the open bottom, the vertical side groove with open ends, the top seat, and central rectangular opening in said seat, of the notched cap-plate, the perforated notched tumblers M N, the upper and lower stop-pins, P P,in said tumbler M, tumbler L, with stop-pin P in its upper face and slottedsleeve J J, projecting from its lower-face, the interposed washers K, the 15 graduated base-tumbler H, with stop-pin H in its upper face, the grooved journal, the spiral spring, and the hasp with the arm having guards S, substantially as specified.

In testimony whereof I aflix my signature Ill :0 presence of two witnesses.
